Looking for fic recs for BBC Sherlock

So, I can easily find all the fics I might want that portray Sherlock as gay (or at least gay where John is concerned) and can also easily find fics that portray Sherlock as asexual. I suppose if I really wanted to I could find fics where he is straight, or straight and abstinent (or is that only in Moffat’s mind?).

But that’s not what I’m interested in. What I’m interested in is something that I don’t see talked about where Sherlock is concerned: I’m curious if anyone can recommend fics where there is something fundamentally broken with Sherlock’s sexuality. Not something where everything is made better after meeting the right person or something like that, but something that portrays him as genuinely dysfunctional. Anything?
